Takealot is bad for business

Takealot is run by a bunch of *******. They advertise a item for R230,00 I purchased it online they tell me that it will be delivered in 2 weeks time 2 weeks go by they send me an email telling me that the suppliers don't have stock couldn't they have told me that the day I purchased the item. I go back to my order box on the app the item is still there but now the price is R399,00. Takealot is weak I think Amazon will finally sink them.
